Question

While dusting a carpet, we give a sudden jerk to it with a stick. Because

• A. The inertia of motion removes the dust
• B. The jerks compensate for the force of adhesion between the dust and the carpet, and dust is removed
• C. The inertia of rest keeps the dust in position and the dust gets removed as the carpet moves away
• D. No inertia is involved in the process, it is simply due to the practical experiences

Answer 1

The correct option is C The inertia of rest keeps the dust in position and the dust gets removed as the carpet moves away

Due to Inertia of rest, a body tends to be in rest or will oppose any motion. That is why the inertia of rest keeps the dust in position and the dust gets removed as the carpet moves away.
